Production device, system, and method

ABSTRACT

In one embodiment of the present invention, a production device which produces a medical product and analyzes a starting material and a central management device which determines processing conditions in the production device are provided separately. In addition, by transmitting and receiving data and the like pertaining to the starting material between the production device and central management device data, the medical product is produced while production conditions therefor are continuously optimized. Thus, it is easy to produce a medical product while reducing or eliminating effects from changes in cells and tissues over time, from oscillation during transport, and from changes in surrounding environment such as changes in temperature, and to produce the desired medical product even when there are individual differences in the starting material.

TECHNICAL FIELD

The present invention relates to a production device, a system, and a method. For example, one embodiment of the present invention relates to a production device, a system, and a method for producing a product that is used for processing human or animal cells or tissues, for reconstructing, repairing, or forming a structure or a function of a body, or for treating or preventing diseases.

BACKGROUND ART

In Japan, it is often necessary to conduct mass and long-term non-clinical and clinical trials (clinical trials) in order to receive pharmaceuticals approval. Therefore, even when an effective pharmaceuticals is invented, patients often have to wait for approval.

In 2014, Japanese Pharmaceutical Affairs Law was revised. As a result of the revision, a new category of “regenerative medicine products” was established in the Pharmaceutical Affairs Law. For “regenerative medicine products” newly introduced, if safety is confirmed and efficacy is estimated, a conditional approval system that can be approved early has been introduced. As a result, it is highly likely to provide new therapeutic agents for various diseases at an early stage.

Among the “regenerative medicine products”, products using microorganism-derived cells or tissues as starting materials are largely classified into “autologous products” and “allogeneic products”. The “autologous products” are those that are produced by processing the starting material collected from a patient and used by the same patient. The “allogeneic products” are those that are produced by processing a starting material collected from a healthy person (different from a patient) and are used by the patient. There are individual differences in cells or tissues, and performance and quality of the cells or tissues can change over time, change due to external forces such as oscillation accompanying during transport, or change from changes in surrounding environment. Therefore, it is impossible or extremely difficult to prepare a large amount of starting material with uniform performance and quality. In addition, when the starting material is not uniform, it is difficult to set appropriate production conditions. Thus, when a process (for example, cell cultivation) that showed good results at the research stage (small or proprietary production) is diverted to a commercial stage (mass or general-purpose production), similarly, good results are not always shown. In the worst case, the performance and quality of the cells or tissues may deviate during the process, and thus there is a possibility that the “regenerative medicine products” cannot be produced.

In order to establish a production process of the “regenerative medicine products”, there has been proposed a quality-by-design (QbD) approach (see Non Patent Literature 1). The QbD approach is a pharmaceuticals quality management approach based on scientific knowledge and risk management (see operation guideline Q8 (formulation development), Q9 (quality risk management), and Q10 (pharmaceuticals quality system) for maintaining safety and quality defined in International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use: ICH).

In short, in the QbD approach, the production process is systematically managed in the following order.

(I) Set quality target product profile (QTPP) of a final product and critical quality attribute (CQA) of the final product that has a strong influence on the QTPP.

(II) Specify critical process parameter (CPP) that affect the performance and quality of the final product based on risk assessment and multivariate experiment.

(III) Define the range (hereinafter, referred to as “design space”) of the CQA and the CPP required to secure QTPP.

In this specification, the QTPP is a product design standard. That is, the QTPP means a summary of the expected quality characteristics of formulation that should be achieved to ensure the required quality when considering the safety and effectiveness of the formulation. In addition, the CQA means physical, chemical, biological, microbiological characteristics or properties that should be within appropriate limits, ranges, and distributions to ensure the required product quality. In addition, the CPP means parameters whose variations affect the CQA and therefore parameters that should be monitored or managed to ensure that the quality required in the process is obtained, among the process parameters.

SUMMARY OF INVENTION Technical Problem

As described above, it is impossible or extremely difficult to prepare a large amount of starting materials (cells or tissues) with uniform performance and quality, and as a result, it is not easy to apply a QbD approach to “regenerative medicine products”. Thus, one embodiment of the present invention is to facilitate production of “regenerative medicine products” using a QbD approach.

According to another embodiment of the present invention, a method for producing a medical product in a production device controlled by a central management device includes generating, by the production device, initial analysis data of human or animal cell that is a starting material of the medical product, transmitting, by the production device, the initial analysis data to the central management device, generating, by the central management device, initial processing data indicating a processing condition of the starting material optimized based on the initial analysis data within a range of a predetermined design space as a processing condition of the starting material, transmitting, by the central management device, the initial processing data to the production device, and processing, by the production device, the starting material according to the initial processing data.

2. Sequence of System

FIGS. 6 to 9 are diagrams showing an example of a sequence of a system shown in FIG. 1. Hereinafter, each sequence will be described in detail.

(1) As to Sequence Shown in FIG. 6

First, in the production device 10, the analysis of the human or animal cells or tissues, which are the starting materials of the medical product, is performed (S11). Note that examples of the analysis may include measurement of a size, a color tone, a weight, a cell particle size, expression rates of various cell surface antigen, the amount of various gene expression, the number of viable cells, or a viable cell rate of human or animal cell or tissue which is the starting material, and qualitative and quantitative determination of expressed gene or expressed protein, measurement of drug concentration of the starting material, detection and identification of pathogenic microorganisms or proliferating viruses included in the starting material, and the like. The production device 10 transmits the signal (initial analysis data) indicating the analysis result of the starting material to the central management device 20.

Next, in the central management device 20, the processing conditions of the starting material are determined based on the initial analysis data (S21). Note that the processing conditions are determined within the predetermined design space. The central management device 20 transmits the signal (initial processing data) indicating the processing conditions of the starting material to the production device 10.

Next, in the production device 10, the starting material is processed based on the initial processing data (S12). Examples of the processing includes drying, immersion, dispersion, crushing, centrifugation (including elutriation), various cell separations including adhesion or separation using magnetic bead, introduction of gene using methods such as an electroporation method, a lipofection method, a particle gun method, an ultrasonic method, and a virus vector method or methods not using these methods, modification of genes using various nucleases, cultivation, pressurization/depressurization, shaking, oscillation irradiation, ultrasonic irradiation, magnetic field generation, freezing, thawing, heating, cooling, replacing all or part of media, adjustment of a surface area in a culture vessel, control of a cell concentration by adjusting the amount of medium, control of temperature, illumination, oscillation, current, magnetic field, barometric pressure, and atmosphere, addition of solvents or additives, aseptic filling, and the like.

In the sequence shown in FIG. 6, the medical product is completed by the above process (S13).

In the sequence shown in FIG. 6, the separately provided production device 10 and the production device 10 separately provided from the central management device 20 for determining processing conditions produce a medical product. Thereby, the degree of freedom of the production place of the medical product is increased. As a result, it is easy to produce the medical product while reducing or eliminating effects from the change in the human or animal cells and tissues, which are the starting materials, over time, from the oscillation during transport, and from the change in the surrounding environment such as changes in temperature. In addition, the medical product can also be produced near the patient using the medical product. As a result, it is easy to provide the medical product to the patient while reducing or eliminating effects from the change in the cells and tissues constituting the medical product over time, from the oscillation during transport, and from the change in the surrounding environment such as the change in temperature.

In addition, in the sequence shown in FIG. 6, the processing conditions of the starting material are determined based on the analysis result of the starting material. As a result, it is easy to set the optimal processing conditions for the starting material. As a result, even when there are individual differences in the starting material, it becomes easy to produce the desired medical product.

Note that the medical product produced by the sequence shown in FIG. 6 may be either “autologous product” or “allogeneic product”. However, when the medical product is the “autologous product”, there is a possibility that the quality of cells or tissues (starting materials) collected from a patient may vary greatly depending on the disease state or condition. Even in such a case, in the sequence shown in FIG. 6, since the processing conditions are determined based on the analysis data of the starting material, the medical product can be produced with high accuracy.

(2) As to the Sequence Shown in FIG. 7

First, in the production device 10, not only the analysis (hereinafter referred to as “the former analysis”) of the human or animal cells or tissues which are the starting materials of the medical product, but also the analysis (hereinafter, referred to as “the latter analysis”) body fluids such as blood and saliva collected from human or animals that have provided the starting material, body hair such as hair, nails, and the like (referred to as “body fluid and the like” in this paragraph) is performed (S14). Examples of the former analysis include at least one of measurement of sizes, color tones, weights, cell particle sizes, expression rates of various cell surface antigens, the amount of various gene expressions, the number of viable cells, or viable cell rates of cells or tissues, analysis of expressed gene, detection and identification of pathogenic microorganisms included in the starting material, and detection and identification of proliferating viruses. In addition, examples of the latter analysis include at least one of analysis of properties, compositions, drug concentration, genes, and the like of cells or tissues, and detection and identification of proliferating viruses included in body fluids, and the like. The production device 10 transmits a signal (initial analysis data) indicating the former analysis result and a signal (clinical data) indicating the latter analysis result to the central management device 20.

Next, in the central management device 20, the processing conditions of the starting material are determined based on the initial analysis data and the clinical data (S22). Note that the processing conditions are determined within the predetermined design space. The central management device 20 transmits the signal (initial processing data) indicating the processing conditions to the production device 10.

Next, in the sequence shown in FIG. 7, the same process as the sequence shown in FIG. 6 is performed (S12), and thus the medical product is completed (S13).

The sequence shown in FIG. 7 has the same advantages as the sequence shown in FIG. 6. In addition, the medical product produced by the sequence shown in FIG. 7 may be either “autologous product” or “allogeneic product”. When the medical product is the “autologous product”, the sequence shown in FIG. 7 has the above-described advantages.

As a result, it is easy to set the optimal processing conditions for the starting material. As a result, even when there are individual differences in the starting material, it becomes easy to produce the desired medical product.

The production device 10 transmits the signal (initial analysis data) indicating the analysis result of the intermediate product to the central management device 20.

Next, in the central management device 20, the processing conditions of the intermediate product are determined based on the intermediate analysis data (S23). Note that the processing conditions are determined within the predetermined design space. The central management device 20 transmits the signal (intermediate processing data) indicating the processing conditions of the intermediate product to the production device 10.

Next, in the production device 10, the intermediate product is processed based on the initial processing data (S17). Examples of the processing includes drying, immersion, dispersion, crushing, centrifugation (including elutriation), various cell separations including adhesion or separation using magnetic bead, introduction of gene using methods such as an electroporation method, a lipofection method, a particle gun method, an ultrasonic method, and a virus vector method or methods not using these methods, modification of genes using various nucleases, cultivation, pressurization/depressurization, shaking, oscillation irradiation, ultrasonic irradiation, magnetic field generation, freezing, thawing, heating, cooling, replacing all or part of media, adjustment of a surface area in a culture vessel, control of a cell concentration by adjusting the amount of medium, control of temperature, illumination, oscillation, current, magnetic field, barometric pressure, and atmosphere, addition of solvents or additives, aseptic filling, and the like.

In the sequence shown in FIG. 8, the medical product is completed by the above process (S13).

The sequence shown in FIG. 8 has the same advantages as the sequence shown in FIG. 6. In addition, the medical product produced by the sequence shown in FIG. 8 may be either “autologous product” or “allogeneic product”. When the medical product is the “autologous product”, the sequence shown in FIG. 8 has the above-described advantages.

Further, in the sequence shown in FIG. 8, the production process of the medical product is determined based not only on the analysis result of the starting material but also the analysis result of the intermediate material. As a result, it possible to set the optimal processing conditions for the intermediate product. As a result, it is possible to reduce the probability that the performance and quality of the intermediate product deviate during the production process.

(4) As to the Sequence Shown in FIG. 9

First, the same process as the sequence shown in FIG. 6 is performed (S11, S21, and S12), and thus the medical product is completed (S13).

Next, the analysis of the medical product is performed (S17). Example of the analysis includes at least one of measurement of the number of viable cells or a viable cell rate in the medical product, analysis of cell surface antigens, analysis of various expressed genes, analysis of the amount of various expressed genes, analysis of various cell functions, measurement of concentration of substances in a solvent, measurement of osmotic pressure, analysis of morphology and particle size of cell and distribution thereof, analysis of a color tone, measurement of a weight, detection and identification of pathogenic microorganisms included in the medical product, detection and identification of proliferating viruses, and the like. The production device 10 transmits the signal (final analysis data) indicating the analysis result of the medical product to the central management device 20.

Next, in the central management device 20, the initial analysis data, the initial processing data, and the final analysis data received or generated in this sequence are stored in association with each other (S24). These newly stored data are used as data for machine learning in the central management device 20 (S25).

The sequence shown in FIG. 9 has the same advantages as the sequence shown in FIG. 6. In addition, the medical product produced by the sequence shown in FIG. 9 may be either “autologous product” or “allogeneic product”. When the medical product is the “autologous product”, the sequence shown in FIG. 9 has the above-described advantages.

Further, in the sequence shown in FIG. 9, the central management device 20 uses the newly obtained analysis data and processing data as the machine learning data. As a result, it possible to improve the accuracy of processing conditions determined by the central management device 20 in proportion to the number of analysis data and processing data stored in the central management device 20. As a result, it is possible to reduce the probability that the performance and quality of the human or animal cells or tissues which are the starting materials deviate during the production process.
